Merge tag 'riscv-for-linus-6.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
- A fix to avoid pt_regs aliasing with idle thread stacks on secondary
harts.
- HAVE_ARCH_HUGE_VMAP is enabled on XIP kernels, which fixes boot
issues on XIP systems with huge pages.
- An update to the uABI documentation clarifying that only scalar
misaligned accesses were grandfathered in as supported, as the vector
extension did not exist at the time the uABI was frozen.
- A fix for the recently-added byte/half atomics to avoid losing the
fully ordered decorations.
